Question
Chapter 26.3, Problem 2MC
Summary Introduction
To determine:
In what is the term resting potential is misleading.
Concept introduction:
Resting potential is measured by the concentration of the ions in the fluid on both the side such as inside and outside of the cell membrane as well as the concentration of ion transport protein that are present in the cell membrane. Resting potential is generated when the neurons are in resting phase.
